Our invention relates to mninnnition-heists, such as are used on warships, and has for its object to provide hoisting mochztnisinof simple and strong construction and in which are provided safety appliances both for preventing' the breakdown of the mechanism under unusual strains and also for preventing on zthrupt d... .ent of theloed. with consequent danger and dznnuge, under conditions where such descent might he liable to take place.

A further object we have in view to provide lor the deliver of the ammunition at the top of the hoist without injuigv to the deck casing or to the ammunition.

L (see Figs. 1 and 5) is a sprocket-whee shaft at the top of the trunk B, to which are secured sprocket-wheels I], over which and the sprocket-wheels '(i, secured on the shaft (1?, extend the carrier-chains M, these chains passing through the trunk, through the outer sides of the compartments ii, and through the lateral chambers B B. The carrierchains at proper iz'itcrvals are secured to the carriers M, which carriers of course extend through the chamber B of the trunk and are.

-N (see Figs. '1, 5, and 6) is a rectangular framing secured to the deck A at the top of the hoist-trunk, the framing having hinge members (indicated at N) by which thecover is in part secured and having outwardly-extending hooks N around it to aid in securing the cover in place. The casing N is also, as shown, provided with inwardly-extending brackets N N 620., which support a pivot pin or shaft N ,on or to which is secured the curved face apron N preferably provided on its concave side with the lugs i l, which when the apron is turned outward to the position shown in dotted lines in Fig. 5 rests on the brackets N;

N indicates the cover, which is hinged on the hinge-brackets N and provided with outcorresponding in position to the hooks N and to which, in addition to said hooks, bolts .1. 8 are connected to hold the cover in place.

At one or more points openings .8 are formed in the top of the trunk B, (see Figs. 30, 31, and 35 to ,37, inclusive,) and the upper part of the trunk is here shown, preferably, reinforced by a reinforcing-plate O, similarly slotted, on which is secured the U- shaped bracket 0, which furnishes bearings for a transversely-extend ing shaft 0, on which is pivoted a safety catch-finger (lisaid linger having near its pivot connection with the shaft 0 a shoulder 0 (best shown in Fig. 35) and ,beingprefejrably provided witha rubber cush ion 0 which when the catch-finger is in operative'position rests against the bracket C",

as shown. A spring 0 normally holds the catcl1fingerin extended position, as shown in Fit. 35.

0 is a lever secured in the end of the shat O and extending into one of the side chainbers B of the trunk, where it is connected to a longitudinally-running rod 0".

1s a cover secured over the bracket 0 and parts connected thereto, as shown.

I The lower end of the rod 0 (see Fig. 1) is connected to a lever-arm P, pivoted at it and connected to the handle-lever P and by preference this lever P is used not only for acts-- ating the rod 0 but also as a reversing'lcver for the motor .C, which, as shown, is an electric motor, a reversing mechanism suitable i i I l l i l l ,1 I I drawings, but which may of coursebe of any convenient construction.

Referring now particularly to Figs. 3, 4-, 26, and 27, it will be seen (see Fig. 24) that the sprocket -Whecl F is connected through a sprocket-chain W with a sproclmtnvheel W 2 on the end of ashat't V7, which {see Fig. 26) has a bearing in the casting Qand through a mitergear W and engaged miter-gear R has engaged with a shaft it, also supported in the Q, this shaft having its outer end it, threaded, as shown, and a clutch disk R formed on an intermediate portion, is also a bearing-shoulder R, which supports the annular clutch-rings. Annular ring, S extends between the clutch rings R and S and is formed on its outer surface with ratchet teeth, as indicated atS. T a threaded hub screwing on the threaded portion ii of the shait R and having attached to it the crankarrn T, this hub and crank-arm being pre vented from screwing 0d of the shaft by the stop-- collar R U indicates a ratchet pawl pivoted on a bolt Q, extending out from a casing Q.

V is a loading-platform at the bottom of the trunk, which is, as shown, secured to the top of the housings l) I) V, indicating simply a casing thrown over the gear F.

K, Fig. 1, indicates a safety-pawlor catch. at the top of the trunk, with a pivoted butter X resting upon it.

With regard to the operation of our apparatus itwill be understood that the chain and carriers move upward through the chamber 1) of the trunk B, receiving the ammunition from the platform B and carrying it up to the deck A the ammunition and carrier raisthe pawl X and buffer X and the carrier finally depositing the ammunition on the apron N which is turned out in the position shown in dotted lines in Fig. in which position it protects the casing N and also insures that the amnninitionshall be turned out from thecarricr and iron. the hoist in proper direction. without too abrupt shock.

in our device the hoist can lie-run either by power or by hand. and we provide means for lowering ammunition to the magazinedccl; as well as for hoisting it to the gundeck.- The power mechanism-of course derive its power from the motor (7, which, as described, is connected through gear C? and with a iiowcr-shaft 3!, having the gearwheel F jeurualed onit between the iixed Lil clutch device i inv 776,667

Thus, as shown in Fig. 26, the saint 1", through its first end ioose friction-ch. and through the friction retcnct'dis rotation by lhc p U so iongns the friction devices are in strong engagement with each other. The thrcods oi the end if of the shaft and of nut T are c 1 in such :1 way that =.o hoint the ammunition t the disk S, and c then turns with V V 3 to do from. the direction of its ccth l4 i it is desired to lower the fili 'i" isturncd "1/ i th, of course, the outward on the 1 abutting nut DI'OVit'lQL, for relieve the in of con;- thou-he r u shaft end it,

This safety device, While especially designed and intended for emmunitiondioists, is capable of more general application and is intended to form the subject-matter of another application for Letters Patent, the device being claimed in this application only in its combination with the emmunition-hoish it will of course be understood that the engagement of the gearF F with either the powcndriven ciutch F F or the hand-driven clutch E F" eli'ected by thelever K.

Referring next to the safety-catch in the trunk, it will be obvious that the lever P? being in the position shown in Fig. 1 the safetycntch U will be held in the position shown in Fig. l or Fig. 35 by the action of the spring O, while at the some time it is free to move up out of the way or thcnminunition and carrier when they impinge against it and moving out after they have passed to provide at stop which in case of ln'enlmgc in the mechanism controlling the carrier will arrest the fall of the load onto the magazine-deck. Nhen it is desired to reverse the motion of the curriers and to convey the mnnmnition to the magazine-deck, it is only necessary to shift the lever P, which through its connection with the lever P moves the rod 0 from its' normal position to that shown in dotted lines in Fig. The shelti), turning with the lever and the finger S impinging on the shoulder O" of the snlctylinger pushes it up through the opening ii, so that the ammunition can pass freely downward to the megazine-dcck.

It is, as we have pointed out, desirable that the shifting of the safety-linger: should take place whenever the direction of rotation of the motor and carriers are reversed, and therei ore we prefc to utilize the lover 1" not oniy as :1 means for shifting the safety-finger out of the path of the ammunition, but also as it means for reversing the direction of the motor, which can be readily d0neas, for instance, by the reversing device illustrated in Figs. and 29, or indeed by any other convenient mechanism for reversing an electric or other motor.
